WINDING-MACHINE.

Specification of Letters Patent.

Patented June 24, 1919.

Application filed December 8, 1917. Serial No. 206,155.

To all whom it may concern:

Be it known that I, JOHN W. Ronems, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in VVinding-Machines, of which the following is a specification.

This invention relates to winding machines in which the material is wound into compact packages, as on spools or bobbins, and more particularly to winding machines in which the various wound packages are arranged in axial alinement, and especially horizontally. The invention contemplates the provision of novel means for stopping the rotation of the spools when some predetermined point in the winding has been reached, as when they are fully wound, and which shall be of such character as to permit adjustment thereof not only with reference to any one spool but with reference to all of them.

In the drawings,

Figure 1 is a plan of the essential elements of an ordinary winding machine provided with my stopping means;

Fig. 2 is a front elevation of what is shown in Fig. 1, illustrating one winding unit- Fig. 3 shows the sectional rod on which the braking or stopping devices are mounted, and its supporting brackets;

Fig. 4 is a side elevation of what is shown in Fig. 1, certain parts appearing in section- Fig. 5 is a vertical sectional view through one of the winding units; and

Figs. 6 and 7 are plan and side elevations of one of the braking devices.

a is the upper rail forming a part of the frame of a well-known type of winding machine, I) the brackets thereon in which in upwardly open bearings rest the alined spindles 0 having whirls d which bear on the peripheries of drive wheels 6 fixed on a horizontal shaft f which is suitably rotated, and g are the brackets projecting from rail a in which the suitably reciprocated traverse rail h slides.

a designates spools which are slipped onto the spindles and suitably held to rotate therewith in some well-known manner, the spools being adapted to receive the windings for forming the wound packages, the material being delivered from swiftsy' or other rotary supply elements journaled in the frame of the machine.

For stopping the winding of a package when it has been developed to a predetermined extend I provide a brake device which is set opposite the windings atthe side of the axis of the spool or other receiving device, as 0, which adjoins the driving mem ber e (that is, in the present instance beneath the package) thus when the package builds up to the extend predetermined the Windings will begin to wipe upon the brake device with the efiect of ultimately moving the package-including driven element out of contact with the driving element, so that the former will cease rotating.

The brake device is preferably a broad plate of hard smooth-surface vitreous material, as glass 70, for example. In furtherance of the several objects of my invention a series of brake devices is supported in the machine as follows:

In alined brackets Z secured to the rail 00 is a rod m which is parallel with the axes of the driving and driven members. It may be secured in the end brackets by clamping nuts n screwed on the ends of the rods, which upon loosening the nuts may turn on its own axis in the several brackets. It is preferable, though not necessary, to form the rod in sections, interlocked by a slot 0 and a feather p in the adjoining ends of each two sections, thus to avoid the necessity for clearance at at least one end of the machine in entering it into the brackets if it were made all in one piece. The rod is set somewhat below the axial line of the spools. Fixed on it, opposite each spool, as by a set screw is a collar 1" having a wing t provided with a set screw u. The screw u penetrates the radial slot 4) of the shank or flat projection to of a broad flat holder w to support the plate 70,- when the holder is removed from the wing 23 the plate la, which has a dove-tail connection therewith, as indicated at y, may be moved in its own plane into or out of assembled relation with the holder.

The several brake devices proj ect from the rod m under the respective spools, the smooth top faces of the plates 70 being each set a definite distance from the periphery of the barrel of the empty spool. This distance may vary in each case, according to circumstances, but in any event it will be apparent that When the package develops to such an extent that the outer windings begin to Wipe upon the plate is the entire driven element will be finally liftedout of contact with the driving member and its rotation stopped. Individual adjustment can be accomplished by loosening the set screw q and turning the corresponding brake deviceup or down on the rod as a fulcrum. Or the whole set of brake devices can be adjusted up or down by loosening the nuts n and turning rod m in the brackets Z.

Having thus fully described my invention. what I claim as new and desire to secure by Letters Patent is z In combination, a supporting structure, a plurality of rotary driving members j ournaled therein and having their axes alined, a plurality of rotary driven members also Copies of this patent may be obtained for five cents each, by addressing the jonrnaled in said structure with their axes alined and parallel with the axes of the driving members, said driven members being adapted to receive the package windings and normally held in but movable out of periph eral engagement with the driving members, a rod arranged parallel with the axes of said members and rotatably adjustable on its own axis, means to secure the rod in any position to which it is rotatively adjusted, brake devices, one for each driven member, arranged in position to be wiped by the corresponding growing packages of windings and arranged on and adjustable around said rod as an axis and means, one for each brake device, to secure such brake device in any position to which it is rotatively adjusted around the rod.

In testimony whereof I aflix my signature.
